Like his acclaimed role as the anti-hero, Merle Dixon, in "The Walking Dead," Michael Rooker is finding himself in the middle again – but this time he's a blue-skinned alien in Marvel Studio's "Guardians of the Galaxy," light years away from the zombie-infested, post-apocalyptic Earth of the popular AMC series.

Rooker's "Galaxy" character, Yondu, is interesting in that he's not an out-an-out bad guy, and in some ways, he has a propensity to be good. Walking that fine line is something Rooker, 59, has not only enjoyed in several projects throughout his storied career, but his whole life, and director James Gunn wanted to tap into that experience.

"James wanted to write something for me that I'm good at -- I'm good at doing bad things and still having people like me," Rooker told me, laughing, in a recent interview. "Even as a 10- or 12-year-old, I'd be doing something bad, like climbing trees, and people would yell at me for doing it yet be smiling at the same time. I never understood what was going on with them. The great thing is, it still happening. James wanted to me to have the ability to say and do anything on screen and still have people like me, and dig the performance and dig the way I do it."

Rooker brings a good ol' boy approach to Yondu, a space pirate who takes Peter Quill from Earth as a young boy after his mother's death. After growing up and learning the ways of Yondu's group, the Ravagers, Quill (Chris Pratt) betrays his mentor and keeps for himself a mysterious orb he's stolen from a powerful space lord, only to learn the sphere holds powers far greater than he ever could have imagined.

Like his fellow "Galaxy" cast mates (including Zoe Saldana, Dave Bautista, Bradley Cooper and Vin Diesel), Rooker has the unenviable task of portraying a beloved character whose origins date back more than four decades in the original Marvel comic books. And while he respects the fan's opinions, Rooker said it was a necessity to make changes with the character of Yondu for the sake of the film.

"I don't really worry about all of the reactions, but of course, it's always there in the back of my head," Rooker said. "I know there will be some people who will be disappointed that Yondu doesn't have a big fin on the top of his head, but they have to realize the roof on my spaceship is pretty low. I would have had to duck when I was walking around for the entire production. The change was decided before I got there, and basically I had to take what was in the script and run with it."

For anyone familiar with his character in "The Walking Dead," Rooker has been the subject of makeup artists before as a zombified Merle, so he knew was he was in for to turn Yondu blue.

"We'd start with a three hours of makeup, then we had a little break for food before more makeup and wardrobe, so in total, it was about five-and-a-half hours each time," Rooker recalled. "That's not so bad. For my role in 'Slither' (a 2006 horror comedy, which was also directed by Gunn), it took seven hours to put on and two-and-a-half to take off. Yondu's makeup only took 45 minutes to take off."

And while extensive makeup is a part of the job that some actors dread, Rooker said he loves the process and has absolutely no complaints about it.

"When I go to work, I get to go to a set. It's like a 12-year-old kid saying goodbye to his parents, running out the door and playing all day long, and coming back for supper at night," Rooker enthused. "That's my life now. When I go to the set, it's like going to a playground and doing all kinds of stuff."

And lucky for Rooker, those sets have been filled with a variety of roles in several different genres.

"With 'Guardians' I get to be a blue alien who whistles to use a great weapon. In 'Eight Men Out' I got to play baseball all day long and on 'Days of Thunder' I got to drive race cars. In 'Henry (Portrait of a Serial Killer)' I got to kill people," Rooker said with a laugh. "You get to use your imagination all these sorts of crazy, creative ways. Some ways are quite dramatic, some are hokey and some are fun. You just get to go everywhere."

Charlie Morton pitched five-hit ball for seven innings, Neil Walker hit a review-aided home run and the Pittsburgh Pirates beat the Cincinnati Reds 3-0 Sunday in a testy game in which benches cleared after All-Stars Andrew Mcutchen and Brandon Phillips were hit by pitches.
